Hi all.I've been having an issue with getting HDR working on my pc since re installing windows.So far I have tried:Both DP and HDMITwo different gpus 1070 +980tiDifferent cablesReinstalling display drivers using DDUUsing various older nvidia driversDP firmware update for both GPU'sWhen looking at DXDIAG, I get HDR not supported and Advanced colour not supported, but it recognises my monitor is HDR capable lg 27gn950. I've also noticed not sure if related that regardless of the colour setup I have in nvidia RGB, 4:4:4, 4:2:2 10 bit colour does not seem to apply, it always shows as 8bit

I could turn on the HDR and WCG setting on initially today when I connected a new HDR TV.

Hello,

Thank you for writing to Microsoft Community Forums.

I understand that you are unable to turn on HDR and WCG color settings in Windows 10. This issue might occur due to incompatible drivers.

I suggest you to roll back the display drivers and check if that helps. Refer the steps mentioned below:

1. Press 'Windows
+ R' key together on your Keyboard.

2. Type 'devmgmt.msc' and hit enter.

3. Expand the display adapter option from the list.

4. Right click on the driver and click on 'Properties'.

5. Click on 'Driver' tab and check for 'Roll Back Driver'. If the roll back option is available, roll back the driver and restart the
computer.

If you are still facing issues with color after enabling HDR on your PC and if you’re using an HDMI connection and your display supports HDR over a DisplayPort connection, use DisplayPort instead to connect your PC and display.

• If HDMI is your only option, use that, and then do one of the following:
  

Reduce the frame rate

• 1. Select Settings > System > Display > Advanced display settings, and then select Display adapter properties.
  2. In the display’s Properties box, select the Monitor tab, select 30 Hertz for the Screen refresh rate, and then select OK.

- OR -

Reduce the resolution

• 1. Select Settings > System > Display > Advanced display settings, and then select Display adapter properties
  2. On the Adapter tab, select List All Modes.

In List All Modes, select the setting that includes 1920 by 1080, 60 Hertz, and then select OK.

Hope it helps.

Poor quality text when using HDR

Hi Don,

Thank you for writing to Microsoft Community Forums.

I can understand that it must be difficult for you when things are not working as it should.

1. What is the make and model of the TV and the computer?
   
2. Are you facing the same issue even on computer or is it only with the TV monitor?
   

I would suggest you to follow the steps mentioned below to turn off ClearType for the HDMI output connected to TV keeping your regular computer display. To do so,

1. Click on Start, type in ClearType and click on
   Adjust ClearType text option.
   
2. The ClearType Text Tuner app will be opened on the screen.
   
3. Uncheck > Turn on ClearType and click on
   Next.
   
4. You’ll be able to see the options such as Yes, I want to tune all monitors now and
   No, only tune the monitors that I select.
   
5. Select No, only tune the monitors that I select and click on the preferred monitor (TV) and follow the onscreen prompts.
   
6. On the next page, select a text sample that looks most readable to you and click on the Next button.
   
7. Repeat the same step on subsequent pages. You will see 5 screens with text samples in a row.
   
8. Click on the Finish button to accept the changes you made.
   

Meanwhile, regarding the issue with the distorted colors and text quality I would suggest you to follow the steps below and check if it works for you.

Steps to change the display settings to match the resolution of the display:

1. Press Windows + I key on your keyboard, click on
   System.
   
2. Click on Display.
   
3. You will see an option to Select and rearrange displays, click on the display associated with the TV.
   
4. Scroll down to select the ‘Recommended’ option under
   Scale and layout to Change the size of text, apps, and other items, and
   Resolution.
   

For more information I would also suggest you to refer the article:
HDR and WCG color settings in Windows 10.

Hope it helps.
